Unable to connect to the database error=100 when trying to dbload SAMSYS/SAMINC

Hi,

I just finish to upgrade a customer from Sage 300 2014 to Sage 300 2018 in a Windows Server 2012/SQL Server 2012.

We just upgrade Sage not the server,it is the same. Before open the real companies to convert I try to create and dbload sample data just to enter there first and check everything was OK. But we get that error.

So after we check a few things with SQL server and everything was OK we proceed with convertion and everything was OK. We run Sage 300 2018 directly from server or from Users PCs (all programs at server so we run workstation setup from those machines).

But if we tried to dbload sample data we always get that error!!!

Any idea?
